Study on The Adoption of Historical Record and Chain of Custody By Brazilian Judicial Experts From the Collection to the Disposal of Evidence: A Survey Questionnaire

Abstract

Objective: The aim of this study is to analyze the practices and protocols of the chain of custody adopted by forensic experts in Brazil, with the intent of evaluating the effectiveness and compliance of these procedures in the evidence production process. Theoretical Framework: This research is based on theories of forensic computing and the importance of evidence preservation. It highlights concepts of quality control and standardized practices in the chain of custody, providing a foundation for understanding best practices and relevant protocols. Method: The methodology employed involves administering a specific questionnaire to a group of forensic experts across Brazil. Data was collected to gather information on chain of custody procedures, including collection, acquisition, examination, analysis, transfer, and disposal of evidence. The study aims to measure the adoption and application of standardized practices by these professionals. Results and Discussion: Results revealed significant variations in the adoption of chain of custody practices among forensic experts. The discussion contextualizes these variations in relation to established theories and practices, identifying gaps and weaknesses in protocols and suggesting areas for improvement. Implications of the Research: The implications of this research include potential improvements in evidence preservation practices and the need for greater adherence to standardized protocols, impacting the reliability and credibility of evidence in judicial processes. Originality/Value: This study contributes to the literature by identifying deficiencies in current practices and suggesting directions for enhancement. The relevance is underscored by the need to improve evidence quality and ensure the integrity of judicial processes.
